I'd argue that it is a slightly different (but totally related) bug.
But as you already merged this with #850212, let's handle it as one.

Correct, systemd uses a native unit.
And even if it would not: cgroupfs-mount does "the right thing" under
systemd.

I'd add it to Should-*, not Required-*, as it is perfectly fine to have
a different cgroupfs initializer.
Will discuss with upstream and include in the next upload.
